2. Well, I figured that each hinge has to support 14g of weight, which is pretty obvious. Since they're both the same distance from the CG, then I guess I really only need to find the Forces for both one them. I was thinking that the force in the x direction would just be the hinge's distance from CG in the x direction (and same for the verticle force) multiplied by 14g, but i'm not sure.

If I gave you the initial vertical velocity, the acceleration due to gravity, and the initial height, could you tell me where I am as a function of time? Meaning, could you write an equation for y(t) using only these values that I gave you?
